    ConnectionError: ('Connection aborted.', BadStatusLine(""''''"))

    This error can also occur on Linux and Windows, a more descriptive error messages would be useful for people trying to debug their code.

    I think you made a mistake in your copy and paste or retyping of that line, since it is not valid python syntax.

    What is not explicit about it? It is telling you there was a bad status line, and what the bad status line contents was. (Used to be you couldn't tell, when the badness of the status line was that it was empty, that that was what the error message was saying, but I'm pretty sure we fixed that so that it shows an empty status line as an empty string in the message).

    Perhaps part of your problem is that you are not getting the string representation of the error message. Is that because of your code, or is this representation something the stdlib is generating?

    This is an error wrapping coming from requests.

    https://github.com/kennethreitz/requests/issues/2364

    The Requests team has concluded they can do nothing about this error, I believe the next step up is the python httplib library.

    I wonder the actual error reported in that issue has any relationship to bpo-15082?

    In any case, the error being presented to requests is *accurate*: httplib tried to read the status line and got nothing (the actual text in the linked issue is BadStatusLine("''")). (Note that bpo-7427 was where we fixed the repr, if you are curious).

    I see that requests would like "a better error message". Is there a concrete suggestion for what that better error message would look like?

    Not exactly sure what do you want the Python library to do, but perhaps this is a duplicate of bpo-8450, about making the error less misleading when the connection is closed before _any_ status line is sent. See also bpo-7427.

    Ouch. I assumed the change was made to the repr, not the contents of line (I wasn't involved in that fix). Not that that would actually affect this issue, I think, since Requests doesn't want to "introspect exception objects".

    Hi there, we are experiencing this in tika-python too, see:

    There is hopefully a better RemoteDisconnected exception and documentation in 3.5, thanks to bpo-3566. In Python 2, I think this is the same as bpo-8450.
